The "wide-spread use" doesn't enter into the picture, check out
http://www.lawnotes.com/patent/deadline/public.html for how little can be considered as invalidating public usage.
As far as meeting all of the independent claims of the patent(s), there are at least three areas in the late '80s that weren't considered by the PTO that I believe constitute prior art along these lines- BBSs, FTP sites and conference demonstrations of distributed multimedia. The fact that none of these were in wide-spread usage at the time for video files, mostly because of modem speed restrictions, only makes the examples more difficult to track down is all.
